Hex Flange Head Self-Tapping Screws

Thread and Pitch


Hex flange head self-tapping screws are characterized by a thread specifically designed to form its own mating thread in the material during installation. This configuration allows fast and efficient fastening without the need for pre-tapping operations.
The pointed tip facilitates initial penetration and proper alignment of the screw, ensuring precise and stable installation. The thread geometry provides high holding strength, good pull-out resistance, and reliable long-term fastening performance.
They are particularly suitable for applications on sheet metal, light metals, and, in some cases, plastic materials, helping to reduce assembly time and improve production efficiency.


Head Type


The hex head with integrated flange (washer-style head) is designed to increase the bearing surface during tightening, distributing the clamping force evenly over the material.
The integrated flange acts as a built-in washer, improving fastening stability and reducing the risk of damage to the contact surface. This design also eliminates the need for separate washers, simplifying installation.

Description and Applications

Hex flange head self-tapping screws are widely used in numerous industrial sectors thanks to their strength and versatility.

Typical applications include:

  • Metal fabrication and sheet metal processing

  • Automotive sector

  • Industrial plant engineering

  • Mechanical assemblies

  • Installation of metal structures and technical components

Thanks to the combination of self-tapping thread, hex head, and integrated flange, these screws provide a reliable solution for fast, secure, and durable fastening while ensuring easy installation and long-term stability.


Material and Finish


Hex flange head self-tapping screws are available in different materials and surface finishes, including:

  • Hardened zinc-plated carbon steel (white), for standard applications with good corrosion resistance

  • A2 stainless steel, ideal for humid or moderately corrosive environments

  • A4 stainless steel, recommended for outdoor or highly aggressive environments

The variety of materials ensures high mechanical performance and excellent corrosion protection even in demanding operating conditions.
